Luqmân
In the name of God, Most Gracious, Most Merciful.
[31:16]
"O my son!" (said Luqman), "If there be (but) the weight of a mustard-seed and it were (hidden) in a rock, or (anywhere) in the heavens or on earth, God will bring it forth: for God understands the finest mysteries, (and) is well-acquainted (with them).


* v.16 : Verses 14-15 are not the direct speech of Luqman but flow by way of commentary on his teaching. He was speaking as a father to his son, and he could not very well urge respect for himself and draw the son’s attention to the limitations of filial obedience. These verses may be supposed to be general directions flowing from Luqman’s teaching to men, and not directed to his son; though in either case, as Luqman got wisdom from Allah, it is divine principles that are enunciated.
* The mustard-seed is proverbially a small, minute thing, that people may ordinarily pass by. Not so Allah. Further emphasis is laid by supposing the mustard-seed to be hidden beneath a rock or in the cleft of a rock, or to be lost in the spacious expanse of the earth or of the heavens. To Allah everything is known, and He will bring it forth, i. e., take account of it.
* For Larif as a title applied to Allah, see n. 2844 to xxii. 63.
